Does all the JSON stuff for OpenGuides.
Distributed and installed as part of the OpenGuides project,
not intended for independent installation.
This documentation is probably only useful to OpenGuides developers.

Note: Some of the fields emitted by the JSON generator are taken from the node metadata. The form of this metadata is not mandated by Wiki::Toolkit. Your wiki application should make sure to store some or all of the following metadata when calling write_node:

Returns the timestamp of the RSS feed in POSIX::strftime style ("Tue, 29 Feb 2000 12:34:56 GMT"), which is equivalent to the timestamp of the most recent item in the feed. Takes the same arguments as make_recentchanges_json(). You will most likely need this to print a Last-Modified HTTP header so user-agents can determine whether they need to reload the feed or not.
